Coupe questions:

I just picked up my new 2015 sportsman 570 almost 2 weeks ago. The dealer didn’t say anything about needing to register it. Do I need to? Is there Polaris factory warranty?

Also, when I picked it up from the dealer it had a full tank and was reflecting it on the digital fuel gauge. I’ve only taken it out 3 times and now after I fill it up it’ll show full sometimes but then sometimes it’ll show just under full. I know not being on flat ground can change this but I’ve checked the fuel level on flat ground. Anybody had issues with this?

Thanks!
